AWS Bites

Let's face it: when it comes to AWS, cost is one of the scariest topics!  Why? Mostly because the underlying model can get very complex.  There are too many variables and ultimately it's just hard to predict how much is a given workload going to cost you on AWS. Are going to be bankrupted by this unpredictable cost? Probably not! In this episode, we share some suggestions and tools on how to approach cost when going to AWS. It's not a simple topic, but it's something you need to embrace, learn and get confident with. With a bit of effort, cost will not be so scary anymore and you'll be able to take advantage of all the awesome services and features of AWS without being so worried about cost! 💰 SPONSORS 💰 AWS Bites is sponsored by fourTheorem, an AWS Consulting Partner offering training, cloud migration, and modern application architecture.

AWS Lambda is one of the most famous AWS services these days. If you are just starting with your cloud journey you might be confused about what Lambda actually is, what are the limitations, and when you should be using it or not. In this episode, we provide a beginner-friendly introduction to Lambda and summarise everything there’s to know about it: when to use it and when not, differences with containers, the pricing model, limitations, and integrations. By the end of this episode, we will also chime in with some of our opinions and share whether we believe that Lambda is the future of cloud computing or not!  💰 SPONSORS 💰 AWS Bites is sponsored by fourTheorem (https://fourtheorem.com/). fourTheorem is an AWS Consulting Partner offering training, cloud migration, and modern application architecture.

Confused about Amazon Cognito? This discussion breaks down the key differences between User Pools and Identity Pools. User Pools act as identity providers, while Identity Pools serve as credential brokers. Real-world applications, like e-commerce, illustrate how these tools enhance user authentication and API security. The episode also touches on practical use cases and the benefits of AWS Amplify for seamless integration. Perfect for developers looking to simplify authentication in their apps!

Uploading and downloading files are some of the most common operations for web applications. But let’s face it, as common as they are, they are still challenging features to implement in a reliable and scalable way!  This is especially true for serverless environments where you have strict limits in payload size and you cannot have long-running connections.  So what’s the solution? If you are using S3, pre-signed URLs can help quite a bit!   In this episode of AWS Bites podcast, we are going to learn more about them, and… if you stick until the very end of this episode, we are going to disclose an interesting and quite unknown tip about pre-signed URLs! In this episode, we mentioned the following resources: - Documentation for the pre-signed POST: https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPOST.html - How to upload files from a frontend app using pre-signed URLs (by Borislav Hadzhiev): https://bobbyhadz.com/blog/aws-s3-presigned-url-react - Using pre-signed URLs for multi-part uploads: https://www.altostra.com/blog/multipart-uploads-with-s3-presigned-url - Different architectures and tips for managing uploads to S3 (by Zach Charles): https://zaccharles.medium.com/s3-uploads-proxies-vs-presigned-urls-vs-presigned-posts-9661e2b37932 - Using S3 Object Lambdas to generate and transform S3 files on the fly (By Eoin Shanaghy): https://eoins.medium.com/using-s3-object-lambdas-to-generate-and-transform-on-the-fly-874b0f27fb84 You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS:  https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

Sometimes people talk about an MVP and then say "yeah but we deploy manually" or "we don't have tests yet". Is that really an MVP or is it something else? And what it takes to build a successful MVP when using AWS? In this episode, we discuss the differences between a prototype, a proof of concept, and an MVP. Then we debate about what's the minimum amount of work you need to put in place to have an MVP on AWS. We debate on whether our weshare.click is an MVP or just a prototype and why. Finally, we provide a list of previous episodes that can help to acquire the foundational AWS knowledge that is needed to be able to build an MVP successfully. In this episode, we mentioned the following resources: - The book  "The lean startup" by Eric Ries: http://theleanstartup.com/book - The weshare.click repository: https://github.com/awsbites/weshare.click - The YouTube playlist of all our weshare.click live streams: https://www.youtube.com/watch?v=EfRElTYilyY&list=PLAWXFhe0N1vI1_z-06EzJ22pz95_gBrId - The YouTube playlist of AWS foundational knowledge videos: https://www.youtube.com/watch?v=M6KAb1RQh9E&list=PLAWXFhe0N1vIGgrMh8gyU4q4KPGaIqpIA&index=1 You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS:  https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

AWS Step Functions are all the rage right now! The visual editor is getting better and better and there are always new capabilities like the recently introduced intrinsic functions. In this episode we will try to answer the question “are Step Functions a Low-Code tool”? In the process, we will give our own definition of what Low-Code means, and we will describe the main characteristics of Step Functions and try to assess whether they match our definition or not. We will also discuss several practical use cases that can be addressed with Low-Code and Step Functions. In this episode, we mentioned the following resources: - Our previous episode dedicated to Step Functions and what can you do with them: https://awsbites.com/7-when-do-you-use-step-functions/ - FullStack Bulletin Newsletter - https://fullstackbulletin.com/ - Implementing the Saga pattern with Step Functions: https://theburningmonk.com/2017/07/applying-the-saga-pattern-with-aws-lambda-and-step-functions/ You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS: https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

How can you build a WeTransfer or a Dropbox Transfer clone on AWS?  This is our sixth (and last!) live coding stream. In this episode, we completed the authentication layer for our file transfer application. Specifically, we completed the OAuth 2 device flow on top of AWS Cognito and updated the weshare CLI application to support this new authentication flow. We also added an authorization layer in front of our file upload API. All our code is available in this repository: https://github.com/awsbites/weshare.click In this episode we mentioned the following resources: GitHub PR with the final OAuth 2.0 device flow step: https://github.com/awsbites/weshare.click/pull/2 jwtinfo CLI tool: https://github.com/lmammino/jwtinfo enquirer package: https://npm.im/enquirer undici HTTP client package: https://npm.im/undici open package to open the browser at a specific URL: https://npm.im/open ora: animated spinner package: https://npm.im/ora conf package for persisting user settings: https://npm.im/conf You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS:  https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?

How can you build a WeTransfer or a Dropbox Transfer clone on AWS?  This is our fifth live coding stream. In this episode, we continued adding some security to our application. Specifically, we implemented 75% of the OAuth 2 device flow on top of AWS Cognito to allow our file upload CLI application to get some credentials. In order to implement this flow, we need to store some secrets. We decided to use DynamoDB and spent a lot of time discussing our data design and how and why we used the famous and controversial DynamoDB single table design principle. All our code is available in this repository: https://github.com/awsbites/weshare.click In this episode we mentioned the following resources: OAuth 2 Device Auth flow RFC8628: https://www.rfc-editor.org/rfc/rfc8628 The DynamoDB book by Alex DeBrie: https://www.dynamodbbook.com/ LevelDB: https://github.com/google/leveldb OAuth 2 Authorization framework RFC6749: https://www.rfc-editor.org/rfc/rfc6749 You can listen to AWS Bites wherever you get your podcasts: - Apple Podcasts: https://podcasts.apple.com/us/podcast/aws-bites/id1585489017 - Spotify: https://open.spotify.com/show/3Lh7PzqBFV6yt5WsTAmO5q - Google: https://podcasts.google.com/feed/aHR0cHM6Ly9hbmNob3IuZm0vcy82YTMzMTJhMC9wb2RjYXN0L3Jzcw== - Breaker: https://www.breaker.audio/aws-bites - RSS:  https://anchor.fm/s/6a3312a0/podcast/rss Do you have any AWS questions you would like us to address?
